As Blue One retired he relaxed, and turned his mind to ideas for filling the evening. He hoped Henry would televise: Robert had news for him.

After a short nap and dinner, he took the elevator to his three-story tower and turned on the television robot. Seating himself in a comfortable armchair, he directed the machine from one channel to another. For some time, there was no answer to his perfunctory call signals, but one of his few acquaintances finally came on.
